The VS-19TQ015... Schottky rectifier has been optimized for
ultralow forward voltage drop specifically for the OR-ing of
parallel power supplies. The proprietary barrier technology
allows for reliable operation up to 125 °C junction
temperature. Typical applications are in parallel switching
power supplies, converters, reverse battery protection, and
redundant power subsystems.
